WOOD-EMBOSSING MACHINE.

Specification of Letters Patent.

Application filed September 20, 1905. Serial No. 279,341.

To all whom 79l fl/lL/ concern:

Be it known that I, JOHN J AMES PowELL, a citizen of the United States, residing at Logan, in the county of Cache and State of Utah, have invented a new and useful Wood- Embossing Machine, of which the following is a specification.

This invention relates to wood-embossing machines.

The object of the invention is to provide a machine of this character in which the embossing-roll shall produce designs of novel and attractive appearance upon the surface of the wood that shall closely resemble the grain of any wood it is desired to imitate, whereby wood of inferior quality may be utilized for purposes for which it would other wise be unfit.

WVith the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel contruction and combination of parts of a wood-embossing machine, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate correspond ing parts, Figure 1 is a view in perspective of a machine constructed in accordance with the present invention. Fig. 2 is an enlargeddetail view, partly in section, of the embossing-roller.

The frame of the machine embodies a base 1, to which are secured, at the opposite ends thereof, two pairs of standards 2, the upper ends of which are connected and rendered rigid by a brace-rod 3. Secured to the standards by nuts 4 is a pair of plates 5, having intermediate of their ends threaded orifices to be engaged by a pair of adjusting-screws 6, that carry cranks 7, by which they may be turned. The lower ends of the screws have combined with them guides 7, which work between the standards, the connection between the screws and the guides being effected by pins 8, that engage grooves 9 in the lower terminals of the screws, thereby to permit the latter freely to be turned relatively to the guides to hold them positively combined therewith. Working in the guides 7 is a shaft 10, carrying an embossing-roller 11, one end of the shaft being reduced at 12 and has combined with it a crank 13, by which it may be turned.

The embossing-roller, which constitutes the gist of the present invention, maybe made solid, as shown, or be constructed of a series of disks suitably assembled, the former construction, however, being preferable. The periphery of the disk is provided with two series of spirally-disposed embossing-ribs 14 and 15, one of the series being right-handed and the other lefthanded, as clearly shown in Fig. 1. In order to enhance the beauty of the grain produced by the ribs, the latter are routed or cut away at 16, resulting thereby in the production of a quartered-stock effect to the wood subjected to the action of the roller. The roller is held combined with the shaft 9 by two collars 17, carrying set-screws 18, the shaft being provided with a keyway 19 to be engaged by a key (not shown) carried by the roller, whereby the latter is prevented from turning independently of the shaft. Arranged below the guides 9 are two similar guides 20, that carry a roller 21, upon which the wood travels in being fed through the machine, the roller being free to revolve in the guides.

In the use of the apparatus a piece of wood of any desired thickness is placed beneath the embossing-roller and the cranks 7 are actuated to cause the embossing-ribs to sink into the grain of the wood the desired depth, and thereafter the crank 13 is rotated, thus drawing the wood through the machine and effecting the embossing of its surface.

The operation of the machine is exceedingly rapid and accurate and will result in the production of highly-artistic effects.

I claim An embossing-roller provided with peripheral right and left hand spirally-disposed embossing-ribs that diverge from the center of the roller to its ends, and have portions routed or removed.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JOHN JAMES POW'ELL.
